SPECIFICATION forming part of Letters Patent No. 550,776, dated December3, 1895.

Application filed nach 25,1895.

To all whom it may concern: Be it known that I, Louis fMARoELLUsBOURGEOIS, Jr. a citizen ofthe United States, residing at New Orleans,in the parish of Orleans and State of Louisiana, have invented certainnew and useful Improvements in Vaporizers and Garburetors and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in apparatus for carbureting air,for the purpose of makinginflammable gas; an d it consists of certainnovel features hereinafter described and claimed.

Reference is had to the accompanying drawings, in which the same partsare indicated by the same letters throughout both views.

Figure l` represents a vertical central section through the apparatus,and Fig. 2 represents a section along the line 2 2 of Fig. l and lookingdown.

A represents an inclosing-chamber which may be cylindrical or of anyother preferred shape, but for convenience in manufacture is preferablymade cylindrical. This chamber incloses an inner chamber B, providedwith a conical cap B, terminating in the deliverypipe B2 for carryingoff the carbureted air.

Between the two chambers A and B is an annular gauze screen O, andinclosed within the chamber B are a plurality of gauze screens C',arranged one above the other and preferably detachably mounted on ringsc, secured within the chamber B.

Gasoline is fed into the chamber B by means of the pipe D, whichterminates in a rose or scattering-plate D'. When the pressure of theincoming air is exceeded by that of the column of the gasoline in thechamber B, the gasoline will rise up in the chamber H high enough tooverflow through the pipe G, and. the air-supply should then be shut offuntil the excess of gasoline is carried off by the pipe G.

The air to be carbureted Ais injected through the pipe E, which ispreferably led upward, as at e, around the smoke-stack F or any otherheating-surface, and is then bent over toward the carbureting-chamber,as at c. The said air is caused to pass through the screens C3 SerialNo. 543,124. (No model.)

in ythe pipe E and C in the chamber A, and the carbureted airis carriedoff through the screen C2 in the pipe B2. These various screens C, C2,and C3 serve as a protection against explosion from external causes, onthe wellknown principles of the miners safety-lamp- The operation of thedevice is as follows: A pump, fan, or other suction device (not shown)is applied to the pipe B2, creating a partial vacuum in the chamber B,which is iilled by the iniiow of air from the pipe E, which air willforce the liquid down in the outer chamber below the tops of theapertures b, when the air will bubble up through the liquid I-I and willrise through the screens O, where it is met by the spray from the roseD. A The air is thus brought into intimate contact with the volatileliquid and is thoroughly carbureted before it passes off through thepipe The influx of gasoline through the pipe D may be caused either by aseparate pump (not shown) or by the partial vacuum in the chamber B. i

Instead of the smoke-stack F the pipe E may be jaclceted about thesteam-cylinder or any other heating-surface.

It will be obvious that various modifications of the herein-describedapparatus might be made which could be used without departing from thespirit of my invention.

Having thus described my in vention,what I claim, and desire to secureby Letters Patent of the United States, is-

l. In an apparatus of the character described, the combination with anouter vessel partly filled with volatile inflammable fluid, of an innerinclosed vessel contained in said outer vessel and provided withperforations near its base and beneath the surface of the said volatilefluid, a screen extending between said vessels and above the surface ofsaid fluid, a plurality of screens stretched across the inner vessel,means for spraying the volatile liuid on said inner screens, andpassages for air through the space between the two vessels, and throughthe several screens, substantially as and for the purposes described. 2.In an apparatus of' the character described, the combination with anouter vessel partly fi-lled with a volatile inflammable liquid, of aninner vessel inclosed in said outer vessel and provided withperforations near its IOO base and beneath the surface of the saidvolatile liquid, a screen extending between said vessels and above thesurface of said liquid, a plurality of screens stretched across theinner vessel, means for spraying the volatile liquid on said screens inthe inner vessel, a pipe for admitting air into the top of the outervessel, and a pipe for drawing off air from the top of the inner vessel,With gauze screens in each of said pipes, substantially as and for thepurposes described.

3. In an apparatus of the character described, the combination with anouter vessel partly filled With a volatile inflammable liquid, of aninner vessel inclosed in said outer vessel and provided Withperforations near its base and beneath the surface of the said volatileliquid, a gauze screen interposed between the two vessels above thesurface of said liquid, and through which the incoming air has to pass,a plurality of screens stretched across the inner vessel, means forspraying,` the volatile liquid on said screens in the inner vessel, apipe for conveying hot air into the upper portion of the outer chamber,a pipe for drawing off the carbureted products from the top of the innerchamber, gauze screens in both of the said pipes, and means for keepingthe surface of said liquid at a predetermined height, substantially asand for the purposes described.

In testimony whereof I affix my signature in presence of two Witnesses.
